Question

to make chocolate cake ,red a requires 2 1/2 kg of maida ,4/5 kg of sugar and 3/20 kg of coco powder . find the weight of the mixture when these three ingredients are mixed together​

Answer 1

Answer:

3 $\frac{9}{20}$ kg

Step-by-step explanation:

Weight of maida = 2 $\frac{1}{2}$ kg

2 $\frac{1}{2}$ converted to improper fraction = $\frac{(2 * 2) + 1}{2}$ = $\frac{4 + 1}{2}$ =  $\frac{5}{2}$

Weight of sugar = $\frac{4}{5}$ kg

Weight of cocoa powder = $\frac{3}{20}$ kg

∴ Weight of mixture when all 3 ingredients are mixed together = $\frac{5}{2}$ + $\frac{4}{5}$ + $\frac{3}{20}$

L.C.M of denominators ( 2, 5, 20) = 20

∴  $\frac{5 * 10}{2 * 10}$ = $\frac{50}{20}$

    $\frac{4 * 4}{5 * 4}$ = $\frac{16}{20}$

    $\frac{3*1}{20*1}$ = $\frac{3}{20}$

$\frac{50}{20} + \frac{16}{20} + \frac{3}{20}$ = $\frac{50 + 16 + 3}{20}$  = $\frac{66 + 3}{20}$ = $\frac{69}{20}$

$\frac{69}{20}$ converted to mixed fraction =  3 $\frac{9}{20}$

∴ Weight of mixture when all 3 ingredients are mixed together = 3 $\frac{9}{20}$ kg

Hope this helps!!!!!
